Laser biosensors for drug discovery

Summary form only given. While lasers have been utilized for countless applications since their introduction more than 50 years ago, the demonstration of a laser with a wavelength that can be tuned by selective recognition and detection of biomolecules has occurred only recently. The high intensity and narrow linewidth properties of the stimulated emission process are highly advantageous for biosensing applications requiring detection of the smallest analytes, such as drug molecules, with high resolution.
